This invention,which is an improvement on a patent granted to me on the30th day October, 1883, and numbered 287,695, appertains to the class ofself-binding harvesters, the improvements relating particularly to thecompressing, ejecting, and cord holding, knotting, and cutting devices,and the mechanism which actuates said devices.

The invention consists in the construction and arrangement of thevarious parts, hereinpointed out in the appended claims.

'anism will then be described in their For convenience and clearness,the main frame, the attached binder and compressor arms, ejector-rake,and mechanism actuating said arms and rake will be first described. Thecompressor mechanism and binding mechproper order.

In the accompanying drawings,A represents the bed-frame of the machine,of which a is the receiving and a the delivering end.

A is the platform, along which the bundles are discharged, extendingfrom the end a to the end a.

A is a standard, rising from the rear part of the platform at the end a,and having. the

compressor and binder arms pivoted oppositely upon it on its outer andinner sides, respectively, as shown.

a" is a curved cord-directing arm secured to the top of the standard andcarrying the spoolbox a on its rearward extension behind the standard.The front end of the arm is bent downward and inward, and is providedwith an aperture, through which the cord runs to the binder-arm.

a is a spring-plate secured to the side of the Q arm a as shown.

a is a bifurcated lug upon the main frame in rear of the standard A.

a is a sprocket-wheel actuating all parts of the machine and driven by achain from a like wheel secured to-the axle or one of the main wheels.The sprocket-wheel a is journaled on the main frame at the end a, andits shaft carries the crank-arm a, provided with a verticalfriction-roller, a

B is a longitudinally-slotted lever pivoted upon the main frame at theend a, and having at its front end an S-shaped extension, 6. Thefriction-roller a enters the slot of the lever, travels in the-same, andvibrates the lever when the sprocket-wheel rotates.

b is an extension from the rear end of the lever B, provided withavertical pin, b*, at its end.

B is a lever pivoted at the end a of the main frame outside the lever B,and provided at its rear end with the slotted enlargement b into theslot of which the pin 1) enters and vibrates the lever B oppositely tothe lever B. The lever B actuates the compressor and binder arms andbinding mechanism, and thelever B actuates the ej ector-rake.

the long longitudinal guide-slot c, and at thev outer end of said slotwith the vertical lugs c and c, respectively,upon its upper and loweredges.

c is a guide-loop on the rearward surface of the bar 0 outside saidlugs, and c is a flat spring secured to the edge of said bar above theloop 0.

D is a reciprocating bar traveling on the rear surface of the bar 0, andsupported by the loop 0 and slot 0, its inner end being provided with asquare lug, d, which enters said slot and is retained therein by awasher and pin, as shown. The bar. D has on its lower edge therectangular notches d d, the former near its inner and the latter towardits outer end, and upon its upper edge is the rectangular notch d,situated between the former notches, but near the notch d.

d is a laterally-swinging link-bar pivoted to the inner end of the bar Dand to the end of an arm, 11", which extends outward from the bend ofthe lever B, so that the vibration of said lever causes the bar D toreciprocate.

E is the curved binder-arm pivoted near the top of the standard A, andhaving its rearward extension, E, connected by a link, e, to the innerarm of a bifurcated vibrating lever, e, pivoted upon the bracket a e isa link-bar pivoted to the outer arm of the bifurcated lever and to thelower end of a vibratory arm, e, having its upper end pivoted on the lugc.

F is a compressor-arm pivoted on the standard A oppositely to thebinder-arm, and provided with the rearward extension, F, which until itsreturn to the outer side of the notch is connected by the link f to theinner arm of the vibratory bifurcated lever f.

f is a link-bar pivoted to the arm of said lever and to the upper arm ofavibratory bar, f, pivoted at its center upon the lug 0 The lever f ispivoted in the bracket a ,inside the lever e. When the bar D is at itslimit of motion inwardly, the arm 6' and the downwardly-bent end ofthelinkbar e rests upon its upper edge outside the notch d, the lowerend of the arm inclininginward. The link-bar c then holds the levere'inclined, soasto draw down the upper end of the link e and theextension E' and hold up the point of the binderarm. As the bar D movesoutward the bent .end of the bar e and arm as fall into the notch d, andin riding out of the same the arm e is inclined outward, drawing backthe link-bar,

so as to cause the lever e to assume an erect position. The end of thebinder-arm then falls. As the inclination of the arm 6 cannot reverse bythe inward reciprocation of the bar D, the

binder arm must remain down all the time that the arm 6 is inside thenotch and up all the time that it is outside the same; but as the saidnotch is only a slight distance inward from the said arm when the bar Dis at its inward limit of motion, the hinder-arm will fall when the saidlimit is nearly reached, and will rise again just after the beginning ofthe return of the bar D. The upper edge of the bar on either side ofsaid notch consequently gives the proper pauses to the binder-arm, andtheir comparative duration is effected by the position of the notch.When the bar D is at its limit of inward motion, the upper end of thebarf and the upwardly-bent end of the linkbar f are' in the notch d withthe bar f", inclining thence downward and outward, and its lower armagainst a proper stop on the lug a. The link-barf then inclines thelever f, and by means, of the link f keeps the compressor-arm raised. Asthe notch travels with the outward movement of the bar D the inclinationof the barf is reversed, the link-bar f drawn outward, andthecompressor-arm F falls. It remains down until the ends of the barf andlink f have entered and are passing out of the notch d, when a dependinglug, Z, attached to the bar D, inside said notch, strikes the lower armof the bar f, causing its upper arm to engage-against the outer wall ofthe notch and reverse itsincliuation and raise thereby thecompressor-arm, which remains up till the bar f is reversed ininclination by the notch d", as before. The compressor-arm is thusraised and lowered at each inward and outward motion of the bar D, beinglowered slightly before the binding-arm to compress the gavel for thelatter. The lower or outer part of the compressor-arm is recessed fromits outer edge, and has pivoted within the recess F the barf, recessedlongitudinally from its inner edge.

f is a bar lying in the recess of the arm, and having its upper endpivoted in the recess of the bar f The bar f is longitudinally slotted,a pin, f, passing through the slot and through the walls of the recessof the compressor-arm. When the compressor arm falls and strikes the bedplate, the barf is driven upward and throws outward the recessed bar f,driving all loose straw from the gavel that might interfere with thecord on the binderarm.

f" is the compressor-cord, fastened to the compressor-arm at f", thencepassing through the opening f of the same, and thence through an openingin the outer end of the spring f.v

secured to the standard A before descending to the compressor mechanism,hereinafter described.

G is the ejector-rake, having its handle or IIO arm extended outwardbeyond the pivot, and having its inner edge concave, so as to lie andbind on the convex edge of the arm y when the rake is lifted.

g* is a link pivoted to the upper end of the link 9 and to an upwardextension, g, of the slide.

9 is an arm of the link 9, bending over the upper edge of the bar anddescending on the rear side of the same. i The links and g together forma toggle-joint.

g is a laterally-moving link bar pivoted to a rear extension of theslide and to the end of the lever B. When the rake is moved outward, thearm 9 strikes the bar 0 and the toggle'joint is extended, the meetingpoints of the links passing the perpendicular. This motion lifts therake and causes the links 9 to bind on the arm 9, the link g preventingthe former link from falling backward. At the end of the inward motionof the rake a lug, Z, on the bar 0 strikes the arm g", and, bendingoutward the toggle-joint, allows the rake to fall. The compressor-cordfdescends from the springf through a slot in the main frame, runs aroundthe pulleys h h, journaled on brackets secured to the under surface ofthe main frame, and the pulley h, and is secured to a staple on thelower surface of the main frame. The pulley h isjournaled upon the innerend of a longitudinal bar, H, sliding in a slot, h, in the outer bar ofthe frame,and also supported by a stirrup, h", depending from the mainframe. The said bar is provided outside the pulley h with therectangular openings If h the'sides of which converge from abovedownward,and to the outer side of said slots, upon the under side, ithas upon it the lug h having its .outer surface beveled, as shown.

I is a hollow block sliding freely on the bar H, and having secured toits lower surface the longitudinally-extending springhook i. The uppersurface of the block has extending laterally from it the opposite armsor lugs, i and i, and centrally upward from it the pin i which enters alongitudinal slot in the inner end of a laterally-swinging link-bar, t,the outer end of which is pivoted upon the end of the S-shaped extensionI) of the lever B. As the block movesinward,the point ofthespringhook ipasses over t-helug h, the bar H being at rest, with a stop, its, on it,againsta part of the main frame; but when the block begins its outermotion thehook catches against the lug and draws the bar out till astop, h, on the bar strikes against the main frame. The beveledholding-edge of thehook then slides over the lug, and the tension of thecompressorcord and the spring f returns the bar H to its formerposition. When the bar H is drawn outward, the compressor-arm is downand the spring f is bent downward. The bar H is prevented from going toofar inward by the hook j,pivoted upon abracket,j, on the main frame, andhaving its arm j pivoted upon the sliding bar J, the outer end of whichis recessed on its edge and upheld by a bar of the main frame. When theblock I moves inward, its lateral arm i strikes against the shoulder jon the lower edge of the bar J, thereby turning the hook j, and makingits point enter one of the slots h. Vhen the bar-His drawn outwardly,the point of the hook rides over the slots. Arectangular opening is cutat the front inner corner of the platform, and a rectangularplate, K, isbolted to the main frame thereover. V

7c is a transverse depression in the plate K, into which thecompressor-arm descends, and which guides the barf in its outwardmotion.

In is the transverse slot in the plate K, through which the binder-armpasses in its descent.

k is a rectangular slot extending longitudinall y of the platform fromthe rear end of the slot k, and serving a purpose hereinafter explained.

The plate K forms part of frame L, to which the holding, knotting, andcutting devices are attached.

To the plate K is bolted the upwardly-projecting flange of the verticalportion Z ofa plate, Z, which lies parallel with the plate K.

l isaplate parallel tothe platesK and Z,about vertical portion of thelatter.

Z is a bracket depending from the plate Z, and having its edge bent atright angles inward.

Z is a guide-bar, secured at its inner end to the plate Z and at itsouter end to the main frame.

M is ahollow vertical shaft journaled in the plates Z and Z. The upperend of the shaft M above the plate Z carries the horizontal jaw m,having on one side the curved and inclined shoulder m. The lower end ofthe shaft M below the plate Z carries the pinion m The iaw in and upperend of the shaft M is provided with the slot m N is a shaft passingthrough the shaft M. and having pivoted to its upper end the heel of ajaw, a, which forms the lower jaw of the knotter, the jaw at being theupper jaw of the same. Thejaw n is pivoted at n in the slots m The lowerend of the shaft N carries the swiveled block it", provided with lateralarms carrying friction-rollers n n 0 is a hollow block reciprocating onthe bar Z*, and provided on its rear side with the upright lugs O O, byengaging with which'the lateral arm i of the block I reciprocates theblock 0.

o is a horizontal arm extending inward from the block 0, and carrying atits end a slotted bar, P. The bar P has on its upper and lower sidesthestraight longitudinal slots p10, the lower one of which is a guide-slotfor the swiveled block a. On the sides of the frame P are midway betweenthe same, and secured to the the similar longitudinal slot-s,pp, havingthe curved portions 1) 19 into which enter the friction-rollers n, sothat when the said rollers pass over the curved portions 1) the shaft Nis raised and the jaw 12 opened from the jaw m.

P is a straight rack-bar, made on the upper front edge, of the bar P,within the same, and engaging with the pinion m, so that as the said baris reciprocated the shaft M (and consequently the shaft N are rotatedfirst in one direction and then oppositely.

Q is a holder-wheel, journaled on the shaft M, immediately below theplate I, and provided with the teeth q.

q is a spring-hook secured to the block 0, extending inward therefrom,and having its point arranged to engage with the teeth q.

g is a flat spring secured to the lower surface of the plate Z, andacting against the teeth g on the-side of the wheel Q, opposite the hookq, so as to prevent the said hook from rotating the wheel as it movesinward. As the hook moves outward its point catches against a tooth andmoves it outward, causing a'tooth diametrically opposite to bind thecord between itself and the plate Z".

R is a tucking-plate having a curved contour, with its inner edgeconcave. The plate R is pivoted on a vertical post, r, between theplates K and and has on its hub, which surrounds the said post, theshoulder 1", against which the spring r, secured to the plate 2*, actswhen the plate R is rotated.

r is an arm standing inward from the boss of the pla e R, and risaspring-hook secured to the block 0, which slips over said arm whenmoving in ward, and draws the arm back when moving outward, till theinclination of the arm allows it to slip off and lets the spring rreturn the plate R to its first position.

S is a rectangular plate or stripper, moving longitudinally in ways onthe under surface of the plate K below the slot k.

s is a cut-away portion of the plate B, which continues and completesthe slot k when the plate S is at its farthest inward position.

8' is a lever-arm pivoted upon the under surface'of the plate K, andslotted to receive a pin, 8 depending from the plate S.

s is a reciprocating bar pivoted at its inner end on the pin 8, andprovided with the Ion gitndinal slot 8* at its outer end.

s is a pin rising from the block 0, with its upper end in the slot 8',and reciprocating the plate S froln the said block. The function of theplate S is hereinafter explained.

T is the cutter-plate, lying upon the plate I, and having thecutting-edge t. The cutterplate is journaled upon the shaft'M, and hasan arm, t',which is pivoted to a reciprocating bar, t, the outer end ofwhich is provided with a longitudinal slot, t into which passes the pint from the block 0, the said pin reciprocating the bar t, and actuatingthereby the cutter-plate. The platel is cut away at U vertically belowthe slot k in the plate K, to allow the binder-arm to descend to theholder. 7

2 is a twine-guide bar having its ends bentdownward and secured to platel, the said bar standing in such position as to direct the twine intothe open jaws of the knotter. The twineguide 2 lies immediately abovethe cutterplate, the cutting-edge of which moves under it and over therecess or slot U in the plate I. The cord-guide 2 receives the cord asitis carried by the needle to the holder, and supports and guides it tothe proper height to enter the jaws of the knotter. The gavel is pressedback against the compressor-cord by the grain-rake, and thecompressor-arm descends in front of the gavel, carrying the cord downand compressing the gavel, the bar H being drawn outward to give theproper tension to the compressor-cord. The binder-arm then descends andpasses the binding-cord around the gave], and the wheel Q advances onetooth and secures the binding-cord between itself and the plate Z. Theshafts M and N have their jaws to the front of the machine, and theplate R or tucker turns the binding-cord to the side of the jaws, sothat it engages therewith. When the jaws have rotated far enough to keepthe cord from slipping off, the plate R springs back and the shaft Mwinds the cord upon itself. The shoulder mon the said shaft then causesthe cord to slip upon the jaws m and a, forming the loop of the knot.When the shaft M has made about one. and one-half rotations, the jawsare opened by the action of the block n" in the slots 1), lifting theshaft N. The jaws are then in position to catch the binding-cord, whichis directed between them by the bar 2. The guide-bar 2 is of the sameheight above the plate 1 as the shoulder m on the shaft M, and the cordconsequently rises upon the guide-bar to that height and slides alongthe same into proper position to engage the shoulder, the bar having theproper inclination to permit this. After the jaws close on the cord thecutterplate T cuts the cord, and the jaws m and n rotate backward, theplate S drawing the loop off the jaws, thus forming the knot, and thejaws opening during their reverse motion to allow the escape of thesevered ends. 1

The reel-adjusting mechanism shown,while forming part of the describedmachine, pertains to another class,and will form the subject of aseparate application for a Patent bearing Serial No. 157,904, and ofeven date with the present application.

The cutting and conveying mechanism is situated sufliciently in front ofthe binding table and mechanism not to prevent the ac tion of thelatter. The parts may be situated relative to each other similarly tothe parts shown in a patent granted to me on the 30th day of October,1883, N 0. 287,695.
